DNV Grade D460 Shipbuilding Steel Plate Supplier

DNV D460 steel is a high-strength, weldable structural steel plate certified by DNV (Det Norske Veritas), primarily used in demanding shipbuilding, offshore structures, and cold-water marine applications requiring excellent toughness, featuring a minimum yield strength of 460 MPa (67 ksi) and designed for low-temperature service.

Key Characteristics

Grade: DNV D460 (also seen as NV D460).
Strength: Extra-high strength, with a specified minimum yield strength of 460 MPa (67 ksi).
Application: Ideal for shipbuilding, offshore platforms, and structures operating in cold ocean environments (e.g., below -20°C).
Toughness: Offers good Charpy V-notch impact toughness, crucial for marine environments.
Type: A thermomechanically rolled, fine-grain structural steel.
